Arthur E. Keene, MillCreekJnd. Application May 26, 1943, Serial najisasrv 4 Claims.

This invention relates to safety razor construction, the primary object of the invention being to provide a safety razor having a hollow handle portion constitutinga chamber for shaving cream used in shaving, and providing a razor wherein the soap i self-contained.

An important object of the invention is to provide a razor of the self-contained type, having pneumatically controlled means for ejecting shaving cream and delivering the shaving cream to the outer surface of the razor blade holder of the razor. v

A further object of the invention is to provide means for building up air pressure around the flexible shaving cream containing sack so that when the control valve is operated, the shaving cream will be forced from the sack, thereby providing exceptionally sensitive and easily operat ing means for regulating th quantity of shaving cream discharged. 7

Still another object of the invention is to provide means for regulating the stroke of the pump mechanism of the handle, to prevent the inward movement of the movable section of the pump, beyond a predetermined point, to insure against the unseating of the air release valve, when the pump is being operated to build up pressure within the handle of the razor.

With the foregoing and other objects in view,

which will appear as the description proceeds, I" the invention resides in the combination and arrangernent of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein described, may 5? be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawing:

Figure 1 is an elevational view of a safety razor constructed in accordance with the invention.

Figure 2 is a longitudinal sectional view through the device.

Figure 3 is an enlarged sectional view through the pump section of the razor.

Figure 4 is a sectional view taken on line 4-4 of Figure 3.

Referring to the drawing in detail. the razor embodiesa hollow handle section 5 which is formed with internal threads for the reception of the threads 6 of the nozzle 1 of the device. This nozzle 1 is formed with a transversely disposed valve chamber 8 in which the slide valve 9 is mounted, the slide valve 9 being provided with an annular reduced portion l0 adapted to align with the opening H through which the shaving cream discharges from the nozzle, A spring indicated at I2 is seated within the valve opening and bears against the inner end of the valve, normally urging the valve to its closed position as shown by Fig. 2 of the drawing; The outer end-of the bore or opening H, is internally threaded to receive'the threaded shank 13 of the blade holder or guard M of the razor- This threaded shank I3 is hollow and the outer end thereof communicates with the atmosphere, so

that shaving cream may pass directly there- 1 throughand be discharged at the curvedouter surface of the blade holder l4. a Mounted within the handle 5 is a shaving cream containing sack l5, which is of alength to extend an appreciable. distance within the handle, the inner end of the sack being spaced from theinnerend of the handle, as shown. The inner end of the handle is provided with a threaded opening inwhichthe valve-seat I5 is positioned, the Valve seat being so arranged that the tapered valve Il may fit thereagainst and retain air forced into the space between the flexible shaving cream sack l5 and inner end of the handle. The valve I! is mounted on the inner end of the valve stem [8 that moves through the valve, and carries a head I9 on the opposite end thereof, there being provided a coiled spring 20 mounted on the valve stem between the valve l6 and head I 9, so that the head when released, will move outwardly, seating the valve II. It will also be seen that when it is desired to relieve the air pressure within the handle of the razor, it is only necessary to press the head inwardly to open the valve .11. The air pressure within the handle will then be relieved.

Secured to the handle 5, by means of the Washer 2|, is a leather washer 22 which is of a diameter to engage the inner surface of the sleeve 23, that is mounted on the handle for movement longitudinally thereof. Elongated openings indicated at 24 are provided in the outer end of the sleeve 23 and provide openings whereby air released from the space between the flexible shaving cream container, and inner end of the handle of the razor, may be relieved. Secured to the inner surface of the sleeve 23, adjacent'to the inner end thereof, is an enlargement 25 that contacts the outer surface of the handle 5 holding the sleeve against wabbling, as it is being moved longitudinally of the handle in creating air pressure within the handle. A notch indicated at 25 is formed in size to accommodate the enlargement 21 that is secured to the side of the handle 5. Thus it will be seen that due to this construction, the operating stroke of the sleeve 23 may be regulated at the will of an operator. By turning the sleeve 23 slightly, so that the edge of the sleeve will contact the enlargement 21, the operating stroke of the sleeve 23 will be reduced, to prevent the unseati of the valve l1, during the normal pumping operation of the sleeve 23. 7

From the foregoing it will be seen that due to the construction shown and described, a person using the razor, may, by moving the sleeve 23 over the handle 5, build up air pressure in the space between the flexible shaving cream containing sack and handle. By moving the valve 9 to its open position, the air pressure within the handle will operate to eject the shaving cream at the outer surface of the blade holder H for use in shaving. During the shaving operation, should it be desired to add additional shaving cream to the surface of the face being shaved, it is only necessary to al-gain operate the valve, liberating more shaving cream.

After the shaving operation, the operator may relieve the air pressure within the handle, by merely directing slight pressure on the head IS. The movement of the head unseats the valve H and allows the air pressure to exhaust through the openings 2!.

What is claimed is: r

1. In a razor, a hollow handle, a shaving'ma'terial sack within the hollow handle, a blade holder secured to one end of the handle and having a bore communicating with the hollow handle, a pump on one end of the handle and adapted to compress air within the handle against said back, whereby shaving material is forced from the sack onto the blade holder, means for controlling the quantity of material ejected from the sack, and means for relieving air pressure within the handle.

2. In a razor, a hollow handle, a sack for containing shaving material, mounted within the hollow handle, a blade holder mounted at one end of the handle and having a bore in communication with the interior of the hollow handle, a sleeve mounted for sliding movement longitudinally of the handle, a washer secured to one end of the handle and being disposed within the sleeve, said sleeve and washer providing a pump adapted to create air pressure within said handle, when the sleeve is moved over said handle, forcing shaving material from the sack to be delivered to the blade holder, and means adapted to regulate the length of the stroke of the sleeve.

3. In a razor, a hollow handle, a blade holder having a bore communicating with the hollow handle, a sack adapted to contain shaving material, mounted within the handle and adapted to deliver shaving material through the blade holder, a sleeve mounted on the handle and adapted to move longitudinally thereof, a Washer secured to one end of the handle and adapted to cooperate with the sleeve, providing a pump adapted to compress air within thehollow handle, whereby shaving material is forced from the sack, and means adapted to regulate the length of the stroke of the sleeve.

4. In a razor, a hollow handle, a nozzle removabl held within one end of the handle, a razor guard, a hollow threaded shank forming a part of said razor guard, said shank being fitted within the nozzle, a collapsible sack adapted to contain shaving material, mounted Within the handle, and adapted to deliver material to the razor guard for shaving purposes, a sleeve slidably mounted on said hollow handle, a washer secured to one end of the handle and adapted to engage the inner surface of the sleeveprov'idlng a pump adapted to create pressure within said handle, forcing material from the sack, and means for relieving airpressure within the hollow handle.
